How does science solve the problem of obesity

Report
“Obesity is a medical condition in
which excess body fat has accumulated
to the extent that it may have an
adverse effect on health”
("Obesity." Wikipedia)
 In
the United States
(Gould 2012):
• 2 out of every 3 adults
 In
Germany (English
2011) :
• 13.7% of adults are
(62%) are overweight
obese
or obese
• 36.4% are overweight
• Obesity-related illness
treatments cost an
Moderate obesity reduces
estimated $190.2
life expectancy by about 3
billion
years.
Severe obesity can shorten
a person’s life by 10 years.
(University of Oxford, 2009)
 1983
 Hoffmann-La
Roche &
Co., Switzerland
 First
developed to
control harmful
chemicals in the
pancreas
Your stomach and
intestine have enzymes,
called lipases, that break
down fat into smaller
molecules, which are then
absorbed from your
digestive tract.
 Orlistat binds to lipases
keeps them from
digesting the eaten fat
 30% of the fat eaten is
blocked (Orlistat)
 Undigested fat is passed
out in feces

Dose is 3 tablets daily, lasts 12 hours, and can be taken for
1-2 years. Longer if
necessary.

 Orlistat
reduces
body weight by an
average of 5-10%.
 The greatest rate
of weight loss
occurs within the
first six months of
treatment.
 Not
more weight is
lost over 2 years
because only 30% of
the fat is blocked.
 Exercise must be
included in the weight
loss plan
 Losing fat faster can
actually be unhealthy
(Orlistat)
Unknown
A
study found that patients taking Orlistat lost
more weight than those on a placebo: ~9kg
versus 6kg. (Davidson 1999)
 Research
studies
showed that people
taking Orlistat
• had a 60% reduction
in the absorption of
Vitamin E (Melia 1996)
• displayed “vitamin D
levels that were
significantly reduced”
(McDuffie 2002)
 Of
those sampled
who were taking
Orlistat and no
vitamin supplement
(Xenical Indications
and Usage):
• 12% developed a low
level of Vitamin D
• 5.8% developed a low
level of Vitamin E


Vitamin D and Vitamin
A are absorbed with
the fat that you eat
Studies indicate that
Orlistat prevents your
body from absorbing
fat and therefore also
vitamins D and E
People taking Orlistat were
recommended by their doctors to also
take Vitamin supplements 2 hours
before or 2 hours after the use of
Orlistat to offset the effects of vitamin
loss.


Vitamins D helps your body
absorb calcium used in
making bone. The use of
Orlistat could lead to softer
bones that may be more
prone to breaking.
Vitamin E helps maintain a
healthy immune system,
protects cells from
antioxidants, and helps
produce blood cells. The
use of Orlistat could lead to
a weaker immune system.
